0IL-FEEDIN G VALVE.

Application filed December 2, 1916.

To all whom it may concern:

Be it known that I, ALBERT P. KooLER, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Feedin Valves, of which the following is a speci cation.

This invention relates to an oil feeding valve.

One of the objects of the present invention is to provide a simple, substantial, cheaply manufactured valve which is particularly adapted for use where high pressure oil burning systems are employed. Another object of the invention is to provide a valve which is kept on its seat by the oil pressure, which requires no stuffing box, which may be employed either as a straight-way or angle valve, and which has a valve controlled port arrangement that permits an ideal oil regulation whether a small or large fire is employed. Further objects -will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a central, vertical section through the valve.

Fig. 2 is an end view of same.

Fig. 3 is a side elevation of the conical valve.

Fig. 41 is a side elevation, showing a modified form of valve.

Fig. 5 is a plan section on line 55 of Fig. 1.

Referring to the drawings in detail, A indlcates a valve casmg, 1n which 1s formed a central chamber 2. Formed at each end of the casing and also on the bottom thereof are extensions, such. as indicated at 3, 1 and 5; the extension 3 being cored out to form an outlet chamber 6; extension 4 to form an inlet chamber 7 and extension 5 to form a second inlet chamber 8. The inlet chamber 8 is in direct communication with the central chamber 2; in fact, it merely forms a continuation or extension thereof. The chamber 7 is also in direct communication with the central chamber through a port 9.

Formed in the upper end of the central chamber is a conical valve seat 10, and turnably mounted in said seat is a tapered plug valve 11, which is secured on the end of a stem 12. This stem passes through and is Specification of Letters Patent.

. therefore, adapted to be closed by the valve 11. Communication between the port 15 and the chamber 2 may,

however, be established through a groove 16 which is cut inthe face of the valve or through a central port 17, such as shown in the modified form of the valve in Fig. 1.

In actual operation, the valve may be employed either as a straight-way or as an angle valve. Referring to Fig. 1, the central chamber is supplied with oil from any suitable source through a pipe 18; the inlet chamber 7 being in this instance closed by means of a plug 19. The oil thus delivered to the chamber will then pass through the groove 16 and the communicating port 15 into the outlet chamber 6, from where it may discharge through a pipe 20 to an oil burner.

The port 15 is preferably rectangular or slot-shaped and should assume a horizontal position, such as shown in Fig. 2, while the groove 16 is narrow and positioned at right angles thereto. It can, therefore, be seen that the amount of oil escaping to the burner from the central chamber 2 may be regulated to a nicety, as the valve 11 may be turned by means of the handle 14 to a point where the groove 15 barely registers with one end of the slot-shaped port 18, or that it may be turned to assume the position shown in Fig. 2 where a perfect register between the slot and port is shown. It is thus possible to adjust the valve to deliver either a small or a large volume of oil or any intermediate quantity desired. If the piping connections employed are such that a straight-Way feed is more convenient, it is only necessary to remove the plug 19 and insert it in the lower inlet side of the valve, While the pipe 18 is connected with the chamber 7; and as the port 9 assumes a position below the valve 11, it can readily be seen that oil may be delivered to the chamber 2 either from the end, when the valve is used as a straight-way valve, or from the bottom, when it serves as an angle valve.

The inner or bottom wall formed by the groove 16 is approximately parallel to the longitudinal axis of the valve 11, consequently, and due to the groove extending through the conical base of valve 11, a passage is formed which has a large bottom inlet and which affords a straight direct communication with outlet slot 15. This allows the fluid pressure to remove any foreign matter which may col ect by forcing same through slot 15. Further, and since the outer side edges formed by the groove 16 move across the ends of the slot 15, any matter will be cut and then removed by the fluid pressure.

A valve constructed as here shown is simple and substantial and cheap to manufacture. No stufling box is required as the coni cal valve seat and plug valve employed permit the formation of a ground joint. The valve is, furthermore, held against its seat at all times by the nut and also by oil pressure exerted on the bottom or end of the valve.

The materials and finish of the several parts of the valve are otherwise such as the experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Iatent is A valve including a casing having a central chamber with a conical valve seat thereabove, said casing having an outlet slot, an inlet having a port communicating with the chamber, and a conical plug valve in said seat, said valve having a peripheral groove extending axially thereof and at right angles to said slot, said groove extending through the bottom end of the solid valve to form a large inlet and terminating above the rectangular slot and having its said terminal directed outwardly toward the slot.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
